The Homeless Youth Dual Diagnosis Initiative (HYDDI) is a Department of Health and Human Services Youth Homelessness initiative implemented through a partnership between Hope Street and the NorthWestern Mental Health (NWMH), the mental health arm of Melbourne Health. A HYDDI Practitioner is employed by NWMH's Substance Use and Mental Illness Treatment Team (SUMITT) and is co-located at Hope Street.

As part of our wrap-around holistic service for young people experiencing homelessness, we have an onsite specialist youth-focused nurse, Cath Flanagan, through our partnership with the Royal District Nursing Service (RDNS) Homeless Persons Program. She is available three days a week to assist with general health assessments and appropriate referrals to specialist health care, including dental, optical, pathology, sexual health, and pregnancy/parenting support.

The Hope Street in Melton and Hope Street in Whittlesea programs housing support model is delivered in partnership with VincentCare Victoria and consists of various configurations of single units and two bedroom family units. Our close working relationship with VincentCare ensures that young people are provided with quality housing and tenancy management support.
